OK ... to finish the story.
Seeing was still good at 4am when I woke.
Uncovered the scope (very little dew anyhow) & headed for Saturn.
Stunning ! I could see all 6 of the visable moons, Cassini division, shadow on the rings & the Pale brown/yellow cloud belts.
Eta Carina was to good to pass up, the humonclus nebula around Eta, displayed a stunning black lattice structure, over the orange glow of the nebula.
I noticed a few Oroinid meteors as well, hopefully the orionids will put on a good early show before the brightening moon washes them out.
All in all a fantastic night, the best in months
I hope someone else out there had as good a night as we did !
